Subject: [PATCH] platform/x86/amd/pmf: pass the struct by reference
Date:   Tue,  4 Oct 2022 13:10:19 +0500
Message-Id: <20221004081019.619193-1-usama.anjum@collabora.com>

Precedence: bulk

The out structure should be passed by reference instead of passing by
value. This saves the extra copy of the structure.

Fixes: 1738061c9ec8 ("platform/x86/amd/pmf: Add support for CnQF")
